The stretching term in the vorticity transport equation is found to be the main mechanism to reduce the degreeofmixing in axisymmetric plume.
从涡量输运方程出发,分析得出拉伸项的存在降低了轴对称热羽流的混合强度。

Likewise, permanent sediment layers are formed with the fixed conveying speed and a certain higher degreeofmixing ratio which called as Critical mixing ratio.
同样输送速度一定,混合此高至使粉尘物料在管道底部形成永久性沉淀层时,这时的混合比即为临界混合比。

The appearance of the different spectral type for white dwarfs depends mainly on the difference in temperature and internal mixingdegree.
